Tremor 3 shines for its wind holds. Tree reticles are great, pending their design. especially if your planning on holding off for wind. Pretty hard to guess precise hold offs once your below the center horizontal line. In multiple target engagements and differing distances dialing isn't always an option based on time. You might consider the CCH reticle as well. Once you use and understand you will not find them as busy as they appear and the added ability you have to spot and call your impacts can be a plus.
I cant find really good pics of the TMR but after review it wouldn't be my first choice.
I also am looking at the Mark 5 3-18 for what I would call a "DMR" type application. I just bought the Nightforce NX8 2.5-20 and sold it before even mounting as I was disappointed with the eye box. I wish the Mark 5 wasnt a 35 mm tube but believe it may be the best all around value considering its feature set and glass.
